COMBINED SCALE AND SCOOP.

SPECIFICATION forming part of Letters Patent No. 531,954, dated January 1, 1 895.

7 Application filed October 16, 1894. Serial No. 525,364- (No model.)

To aZZ whom it may concern.-

Be it known that I, GoTTHoLn LANGER, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in a Combined Scale and Scoop, of which the following is a full, clear, and exact description, reference being had to the accom panying drawings, forming a part hereof.

My invention relates to an improved weighing scoop and consists in the novel construction, combination and arrangement of parts, hereinafter described and designated in the claims.

The object of my invention is to provide an improved scoop of the class above mentioned which shall operate upon the principle of the common steelyards; which shall be devoid of the usual spring-balance; which shall be very simple in construction, and which shall possess superior advantages over weighing scoops heretofore made use of.

Referring to the drawings: Figure 1 is a plan view of a scoop, embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a side elevation of the same, with the parts in position for weighing. Fig. at is a sectional side elevation of the combined scoop handle and poise detached. Fig. 5 is a sectional plan view of the same taken on the line 5-5 of Fig. 4:. Fig. 6 is an end elevation of the inner end of the combined handle and poise. Fig. 7 is a detail elevation of the base of the bowl. Fig. 8 is a sectional side elevation of portions of thehandle and bowl illustrating a different connection between said parts.

1 indicates the bowl of the scoop having a cover-plate 2 fixed thereon so as to cover about one-half the length of said bowl and close one end of the bowl and leave the opposite end open, whereby powdered material or fluids will be retained within said bowl when the same is tipped, as shown in Fig. 3.

3 indicates the beam which is pivotally connected at one end to the scoop-bowl by means of a bracket 4 fixed upon the cover 2 at such a point that the closed end of said bowl will preponderate in weight. A pin or bolt 5 pivotally connects the beam 3 to the said bracket 4. Said beam is provided with graduation marks 6' intermediate of its ends.

Pivotally connected to the beam 3 at a point adjacent the end which is connected to the bracket 4 is a combined handle-lock and fulcrum 7 carrying at one end a knife-edged pivot 8. The pivot S is preferably made to loosely engage a hole or aperture 9 in said beam. Said combined handle-lock and ful-. crum is preferably made in the form of two parallel links with a loop 9 pivotally connected to the ends of said links which are opposite those to which the knife-edged pivot 8 is connected, so that said loop will perform a double function hereinafter mentioned. Said links are provided upon one edge with a projection or pointer 10, which is adapted to register with a horizontal mark 11 on the side of said beam during operation to show when the beam is balanced. A pin or stop 12 projects from the free end of the beam to limit the outward movement of the handle and poise thereon. Said pin or stop 12 is not contacted by the extreme outer end of said handle, but when said handle is moved outward on the beam, said end thereof may pass considerably 7 5 beyond the end of said beam, said stop 12 passing through the opening in the end of said handle and contacting with projections 12 formed upon the interior of said handle at a point adjacent the inner end thereof.

13 indicates a combined handle and poise, the same having a longitudinal passage and opposite open ends which are engaged by the beam 3 during operation, so that said part 13 may freely slide upon said beam when the scoop is used as a scale. Said handle and poise are normally locked firmly to the bowl 1 by means of the loop 9 loosely engaging over a vertical lug or projection 14: formed upon the inner portion of said part l3.' (See Fig. 2.)

Projecting from the base of the bowl 1, parallel with each other and with the straight upper edge of said bowl, are two pins 15 in the same horizontal plane but in different 5 vertical planes, the inner ends of which are secured to a base-plate 16, which, in turn, is secured to the base of said bowl in any suitable manner. (See Fig. 7.)

When the handle is in the position shown [00 in Fig. 2, the base-plate 16 is contacted by a similar plate 17 carried by the inner end of the part 13, said plate 17 having two suitable apertures 18 which are engaged by the pins 15 to prevent tipping or twisting of said handle and said bowl with respect to each other. In some cases I may use for this purpose the construction shown in Fig.8, wherein a spring 19 has its inner end fixed to the face of the bowl 1 and projects in a horizontal plane viously described.

The outer end of the handle 13 is provided with an opening at a point above the beam opening thereat, and through this opening a common glass spirit-level 22 is inserted and fixed in position within the handle, and formed in the upper edge of the handle is a sight-opening 23 at a point midway of the length of said spirit-level, whereby the beam may be accurately balanced during operation. The opening through which the spirit-level is inserted is closed by a plug 24. A curved spring 25 has one end fixed to the upper edge of the handle 13 upon the interior thereof, so that said spring normally rests upon the upper edge of the said beam 3 and thereby acts as a friction-brake to loosely bind said handle to said beam so that the handle will retain any position upon said beam in which it is placed. (See Fig. 4;.)

A hook 526 is fixed upon the outer surface of the bowl 1 so that bags or packages to be weighed maybe supported on said hook during the weighing operation.

The operation is as follows: When it is desired to weigh powdered or granulated material, the device may be used as a common scoop when the parts are in the position in which they are shown in Figs. 1 and 2. After the material has been placed within the bowl 1 the loop 9 is disengaged from the projection 14 on thehandle and if the spring shown in Fig. 8 is made use of, the free end of said spring is moved upward until the locking lug 21 is above the plane of the loop 20 on the handle, and then said handle may be moved on the beam away from said bowl, which will permit the heavier closed end of said bowl to gravitate downward to the position shown in Fig. 3, and then the operator suspends the entire device by grasping the combined handle-lock and'fulcrum 7, permitting it to occupy a vertical position, as shown in Fig. 3, and the operator then slides the combined handle and poise to the proper position upon the beam to balance the material in the bowl. When the pointer 10 registers with the mark 11 on the said beam and when the air bubble of the spirit-level registers with the opening 23 in the said part 13, the beam will be balanced. lVhen it is desired to weigh packages or bags of material, the same are supported upon the hook 26.

hat I claim is-- 1. The improved weighing scoop, having a bowl, a graduated beam pivotally connected to said bowl, a combined handle and poise mounted to slide upon said beam, means for locking said handle to said beam and bowl when the device is used as a common scoop, and a combined handle-lock and fulcrum pivotally connected to said beam and constructed to lock said handle when the device is used as a common scoop and to suspend the device during the weighing operation, substantially as herein specified.

2. The improved weighing scoop, comprising a bowl,a beam connected to said bowl, a fulcrum whereby said beam may be suspended, a combined handle and poise mounted to slide upon said beam, and a spring 19 having alockinglug 21 and secured at one end to the base of said bowl and engaging said combined handle and poise to lock the same to said bowl, substantially as herein specified.

3. A weighing-scoop having a beam, and a combined handle and poise, said handle and poise being connected to slide together on said beam, substantially as herein specified.

4. The improved weighing-scoop, constructed in the form of steelyards, and com prising ascoop, a beam forming a portion of the lifting handle of said scoop, to one end of which the latter is pivotally connected and thereby suspended, a poise, and an additional handle in the form of a link or loop pivotally connected to said beam, and from which the latter is suspended through the weighing operation, substantially as herein specified.

In testimony whereof I afiiX my signature in presence of two witnesses.

GOTTHOLD LANGER.
